From 78a3b4db2e53a1903c86e2856e175d85a3849e84 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 1 Apr 2009 03:41:09 -0300 Subject: V4L/DVB (11367): v4l2-common: remove legacy code Now that all drivers are converted to v4l2_subdev we can remove legacy code in v4l2-common. Also move the documentation of the internal API to v4l2-subdev.h where it really belongs.
